Car trouble part II

[Pat The Fox]

It's not the wires. Pulled and tested them and the ohmic resistance is proper. Also, fuel is getting in to the cylinder, so that means the injectors are firing.

BCAA does diagnostics? How much are they or do they come with the membership?

A thought is it could be the EGR valve just causing things to run lean, but I'd need to pull codes to see if that is the case and I don't have the equipment to do so.

Spark is going off, fuel is getting in. Starting to sound more like compression issue then.

Could be compression, air/fuel mix (if it's too lean it won't ignite) or just some other weird cause.

Re: Compression issues. I was thinking more along the lines that one of your valves isn't seating properly, or simply isn't opening. Could explain that knocking sound your hearing when you run the engine. One of the things they do to check for compression is to plug a gauge in through your spark plug hole. With the ignition wires off the other plugs, turn the engine over a few times and take a reading.

Usually its just a matter of taking the cam head off and seeing what is going on. But in your case, that will be quite a bit of work in itself.
